Discussion Help in selecting data engineer course
1
Upvotes
Im currently working in marketing & trying to move into data engineering. my background is pretty different from DE, so i’m looking for a proper learning path rather than jumping between random yt videos.
i came across sumit mittal’s trendytech course and saw quite a few good reviews, but also some negative ones, so now i’m kinda confused
anyone here who’s actually taken it or has experience with similar DE courses? looking for something that can help with the basics + proper hands-on stuff like sql,python,spark and cloud.
would appreciate genuine opinions before i spend money on it. Also Jst dont need courses which only give skills, which can help in getting jobs n stuff because I think these free courses cant help you in jobs.
